A Turkish court issued arrest warrants Wednesday for two suspects close to Saudi Crown Prince Mohammed bin Salman over the murder of journalist Jamal Khashoggi, increasing pressure on the kingdom’s de facto leader.

The prosecutor’s office has concluded there is “strong suspicion” that Saud al-Qahtani and General Ahmed al-Asiri, who were removed from their positions in October, were among the planners of the October 2 killing at the Saudi consulate in Istanbul.
